Here's a video showing a bit of the MoJo's durability.

All of the crashes in the beginning of the video did no damage whatsoever. I use Master Airscrew S-2 nylon props. They aren't the most efficient, but they sure can take a beating. I crash the MoJo routinely, and although I've had to make countless minor repairs, nothing has (as of yet) come close to grounding it. It really is one tough bird.

PS - The HQ version on a full screen helps really see how hard the darn thing is hiting the dirt.
